Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.let the center of circle be h,k
then dist between h,k and 1,2 = radius of small circle + radius of variable circle
also dist between 1,4 and h,k < r+radius of big circle
radius of small circle =1 , big = 10
i did the same things as shown in M-2 , but i am getting b=11/2 not a=11/2
just a diff of notations ig
can u send a clearer img tho
Ah, my bad.
And yeah it will be b and not a=11/2
b being semi major axis right?
Yep.
aight
thanx
can u look at the other one too
